We invite submissions for presentations on a symposium at TDWG 2014 on "Standards for mobilising and integrating sample-based data". Those interested should contact the conveners listed below. The closing date for submission is August 1st. Sample-based data is available from thousands of environmental, ecological, and natural resource monitoring programmes. Such data are usually quantitative, calibrated, and follow certain protocols so that changes and trends of populations can be detected. This is in contrast to opportunistic observation and collection data, which today form a significant portion of openly accessible biodiversity data. Sample-based data is often not shared because the underlying protocols have been hard to encode in a standardised way. This symposium will present recent work on a proposal for extending DwC with a minimal set of new properties (e.g., quantity, quantityType, samplingGeometry, samplingUnit, eventSeriesID) that allow encoding of the essential characteristics of sample-based data while drawing on the existing tool and support infrastructure offered by the GBIF Integrated Publishing Toolkit. Presentations on other publishing models for sample-based data are most welcome. We are particularly interested in submissions relating to extension of the Darwin Core Archive model, DataOne/LTER/KNB data integration, application of models such as OGC Observations and Measurements, and in new or emerging technologies such as Veg-X [1], JSON-LD [2] or CSV on the Web [3] [1] http://wiki.tdwg.org/twiki/bin/view/Vegetation/WebHome [2] http://json-ld.org/ [3] http://www.w3.org/2013/05/lcsv-charter.html Conveners Éamonn Ó Tuama (eotuama@gbif.org) Hannu Saarenmaa (hannu.saarenmaa@helsinki.fi) ____________________________________________________ Éamonn Ó Tuama, M.Sc., Ph.D. (eotuama@gbif.org), Senior Programme Officer for Interoperability, Global Biodiversity Information Facility Secretariat, Universitetsparken 15, DK-2100, Copenhagen Ø, DENMARK Phone: +45 3532 1494; Fax: +45 3532 1480
